T15-why no impact ability with rt angle and offset chucks

[Naildrivingman]

Wondering why there is no ability to have the impact feature transferred through the adaptor to the rt angle and offset chucks.  I can see how this would be helpful.

My uneducated guess would be the gear train would not take the stress.

I get that, but wonder how a tiny T10 bit can take the stress of impact.

If the gears are non-metal, then I can see how the impact would affect them.

Think about it for a minute.  [unsure]

How would the linear blows generated by the mechanism in the drill body transfer themselves 90 degrees through the add on chuck ?

Festool is bringing up the rear when it comes to impact drivers and while there are a few dedicated 90deg impacts - they are not big sellers. No way FT is going to wade into that end of the pool.

What type tasks are you doing that would utilize a 90deg impact ?

Impact drills work by having a steel ripple disc rotate against a fixed one.

This explains in part why they aren't very effective in comparison to the pneumatic piston versions, why they're prone to premature wear & why they make such a god-awful noise.

Without a solid, unbroken, continuous link through the drivetrain, the rather miserable shockwaves generated naturally dissipate.  Liken it to using impact bits with rubber shanks.

Use one tiny T10 bit exclusively throughout the tool's entire life and see how it holds up.

I suspect the slight slop/play in the two heads would soak up the impact (which is a slight back and forth) thus nearly negating the blows.  I'm sure that the gears wouldn't like the racking motion either.

No Festool right angle impact is because there isn't a real market for them.

It seems like you're talking about hammer drills where the force pushes the drill bit into the work.  The thread is about impact drivers where the hammering force is in the direction of the rotation of the bit.  A totally different tool with a totally different goal.

There are impact-rated right angle drive adapters for impact drivers, and Makita makes a purpose built right angle impact driver.

If you grind off the pin that disables to impact function from your Ti15 adapter and put the Festool right angle adapter on it you will have a right angle impact driver, though of course you'd void the warranty on the right angle adapter.

As TJ Cornish points out, impact drivers are entirely different tools from rotary hammers and hammer drills. On a side note, do people still use hammer drills? It's been years since I saw one on a job site, nowadays I only see rotary hammers for masonry drilling.

Bosch manufactures a right angle adapter for their 1" rotary SDS-Plus rotary hammers.

I use Milwaukee's 18v right angle impact driver and it works great.  Bought it right after drilling umpteen holes between 12" spaced floor joists.

And how well does it work or last ? I'll bet it's more of a gimmick than anything.

Even if FT decided to pursue this, the t15 doesn't produce enough torque to make an adapter very useful anyway.

If it has enough torque to drive straight, then it has enough torque to drive through angle adapter. What do you think is the loss there? 1-2%?

I don't have any info about performance of the accessory, other than its existence. Probably not great, othwise we'd see Hilti, Metabo, Makita and Milwaukee making them as well.

Product page for the bosch attachment

In the video the guy says it "only" loses 40% of the hammering power. (Nonetheless it looks useful in some situations for me)

Personally I thought the op meant the ti15 in this thread instead of the t15, and that it was about tangential impact instead of linear impact. And I agreed with the first answer, so I didn't feel the need to chime in.

The Milwaukee impactor works fine, I mostly use it for drilling and driving self tapping screws into aluminum and steel but have driven in washer head structural lags with it also.

That is a hammer drill with longitudinal impact. The attachment shown also provides longitudinal impact. Large loss is due to the mass of the drill being not in line with the impact direction. The OP was referring to impact driver for screws with tangential impact where loss will be lower.

I have no doubt a some people could make use of one.  I am also confident that it's not enough for festool to ever come out with one.

rst - are you talking about Milwaukee's  2668-xx ?    Are you using it for close quarters HVAC type work ?

And washer head lag screws...
